A clearer starting point.

Reading the credential and deciding whether it is authorised are separate steps. Match the selected FC7780 output to the receiving host or controller, and define which component controls the door. Confirm any relay option and the actual circuit for the supplied configuration.

A reader in transparent output mode may send the original content, while a protocol or development mode can add a header, length, device information and check data. Select the mode that matches the host application and use the protocol reference for that model and firmware.

First confirm that the reader has started normally and that the code is complete, correctly generated and presented within the usable reading area. For codes shown on a phone, raise the screen brightness and remove glare; if known-good codes still produce no response, record the indicator and buzzer behavior for support.

Tell us which credentials people will use, where the device will be installed, which interfaces are required and what should happen in the software workflow. A mounting drawing, host-equipment description or simple process diagram helps us identify the questions that must be confirmed before recommending a configuration.

No. Credential modules, interfaces, mounting parts, network options and software can vary within the same product family. Confirm the exact model and selected options in writing before designing an enclosure, cable set or integration around it.

Find available documents by model in the download center. If the manual, specification or installation drawing you need is not listed, send the model and configuration to our team so we can identify the matching document.

Start with the credential, mounting, interfaces and software flow that matter to the final installation. Confirm the sample configuration in writing, test it in the intended environment and record any differences before planning a larger rollout.

Include the overseas product model, firmware or software version, connection method and a short sequence that reproduces the issue. Screenshots, indicator behavior and relevant logs help; do not send passwords, access credentials or personal biometric data.

Compare the power supply voltage, current capacity and wiring with the specification for the selected configuration. If the problem continues, record whether it happens at startup or during a particular action and send the model, firmware and observations to technical support.
